In Blender 2.7, i could change the layout with Ctrl + ← and Ctrl + →.
In 2.7, the scene was layout dependent, allowing me to navigate the scene this way.
However, in Blender 2.8, the layout has become the workspace and works completely independent of the scene.
I didn't find anything other than a mouse click to change the scene.
Do you know how to navigate scenes using keyboard shortcuts in 2.8?
